The Reading man who walked naked along the West Shore Bypass after he was thrown from the roof of a minivan had cocaine in his system after the accident, according to court records available Wednesday.

John W. Messerly, 38, told police he had used crack cocaine the night before the April 4 accident and had not slept since then, according to the documents.

Messerly of the 200 block of North Sixth Street was charged Wednesday with driving under the influence, risking a catastrophe, indecent exposure, resisting arrest, public drunkenness and related offenses.

He had been in Berks County Prison without bail on a parole violation since Friday.

Messerly remained in the jail after the charges were filed Wednesday in the office of West Reading District Judge Timothy M. Dougherty.

Bail information was unavailable.

Messerly was driving his employer’s minivan on the bypass in West Reading about 3 p.m. April 4 when he climbed out of the driver-side window, stood on the roof and was catapulted into the woods when the van crashed into a guide rail, borough police said.

He suffered a severe cut to his abdomen and spent three days in Reading Hospital, officials said.

Investigators said they still do not know why Messerly climbed out of the moving minivan.

According to court records:

Officers from West Reading and Wyomissing responded to the bypass for a report of a naked man running along the road.

When they arrived, the officers were confronted by a nude Messerly, who came toward them and ignored orders to stop. Two of the officers used Taser stun guns on Messerly to try to stop him.

Messerly fell to the ground, but got up as the officers approached him. A third officer hit Messerly in the back with a Taser, which briefly stunned him.

Messerly still refused to heed the officers’ orders and started toward them again.

One of the officers sprayed Messerly in the face with pepper spray, another hit him in the back with a baton and another reactivated one of the Tasers.

Messerly still refused to cooperate.

After a second shot of pepper spray to his face, another hit to his back with a baton and a fifth jolt from a Taser, Messerly was taken to the ground and handcuffed.

Two witnesses reported seeing Messerly climb out of the driver’s side window of a moving minivan and onto its roof.

Toxicology tests showed that Messerly had cocaine in his system when he was admitted to the hospital, according to the court records.

Messerly later admitted to police that he had used crack cocaine the night before the accident. He also told police he had not slept from the time he used the cocaine until after the accident.

In an interview with police and a separate interview with the Reading Eagle, Messerly denied climbing onto the roof of the van.

He said he was adjusting lumber that had come loose inside the minivan when he was thrown out the passenger-side window.

Messerly said he climbed an embankment to get back onto the highway to seek help. He said he took his clothes off because he was in shock and wanted to see if he had any internal injuries.
